MINERS LAMP.

Application filed January 3, 1924. Serial No. 684,211;

, To all whom it may concern."

Be it known that I, JosnrH MENAPAOE, a subject of the King of Italy, residing at Latuda, in the county of Carbon and State of Utah, have invented certain new and use i. ful Improvements in Miners Lamps, of which the following is a spec1ficat1on.-

. is provided with an intermediate chamber constructed to provide a tortuous passage and filled with a suitable, gas filtering material or packing through which the gas generated in the lower, carbide chambei passes to the burner tip. I

With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying'drawing and claimed. a

In the drawing, wherein like reference characters designate corresponding parts throughout the several views.

Figure 5 is a horizontal sectional view taken on line VV of 2 looking upwardly, and showing the tortuous passage filled with packing or filtering material in the gas filtering chamber,

Figure 6 shows side elevational views of the valve structure controlling the flow of gas to the burner tip, and

Figure 7 is a side elevational view of a lamp pick carried by the lamp.

Referring more in detail to the accompanying drawing, there is illustrated a miners carbide. lamp including a casing, preferably of cylindrical formation and embodying upper and lower sections 1 and 2 respectively having athreaded connection 3. as shown in Fig. 2. The lower end of the upper section 1 that is connected to the lower section 2 is provided with a gas filtering chamber embodying upperand lower walls 4 and 5 formed integral with the upper section 1 and connected by an outer annular wall 6 provided with outwardly directed protuberances 7 to facilitate gripping of the upper section when the same is mounted upon the lower section 2, The upper and lower walls' 4 and 5 of the gas filtering" chamber are provided with axial openings through which the tubular member 8' extends to form a closure therefor as shown in F ig."

2, and to render the gas chamber air tight. The gas chamberis provided with a series of internal baffles or veins 9 and 10 of the form illustrated in Fig. 5 to provide tortuousrpassages 11, 12 and 13 as indicated by the arrows and through which passages the gasfiows, j

The tubular member 8 extending through the gas chamber projects downwardly into the lower section 2 of the lamp casing and is downwardly tapered as at 8 with the terminal lower end thereof further tapered as at 8 to form a valve seat. Anenlargement of screw formation as shown at 8 in Fig. 2-is formed adjacent the upper end of they tubular member 8 withinthe upper section land is preferably formed integral with the top wall 14 of the uppersection. A valve stem 15 is positioned in the tubular member 8 and has a tapering valve 15? at itslower end that engages the valveseat 8 and further carries a needle point 15 projecting through the lower open end of the tubular member 8 to clear a water passage therethrough. The upper end of the valve stem c carries an enlarged screw block 15 working in the enlarged threaded por-' tion 8 of the tubular member and further carries an operating head 16 disposed above the top wall 14 of the upper section 1 for manipulating the valve stem 15. Water W is placed in the upper section 1 of the lamp casing through an opening in the top wall 14 thereof that is closed by the hinged stopper 17 and carbide C is placed in the lower section 2 of the lamp when the upper and lower sections are separated at their threaded connection. Side openings 18 are formed in the tubular member 8 adjacent the upper Wall 4 of the gas chamber and when the lar member and escapes at the lower open end thereof into the lower section or carbide chamber. 7

The tortuous passages in the gas chamber are filled with packing orfiltering material 1.9 and the flowing of'gas generated in the lower section 2 to the gas chamber is controlled. by. valve .meehanisin includinga tubular-member2o that extends from the top vcapable of ready extraction for cleaning the A hook 37 is as walll l of thel nppersection 1 downwardly through the. lower wall 5 of the gas chamberv at one end of the passage 11 as shown in Eigs..2 and 5. The. tubular member within the gas chamber] is provided witha sideljopening 21 and a valve stem 22 ro-.

theopening and closing ofthe opening 21. The val estem 22 carries an outwardly .directedannular flange 23 at its lower end that engageslthe bottom -wall.5 of the gas chamber and the lower end of said valve stem is provided with an angle opening having an axial 1 portion ,24Qextending through the lower endofthe valvestem 22 and a co municating side opening 25 locatedwithin the ,tubular memb er 20 and adapted-.tOQbe moved into registration with theopen ing 2,1. in sald tubular member upon rotation of the,

valvestem. A key end 26 is carriedithe upper, endv of the valve stem 22 and up'on which a handle 27 is fixed as shownin Eigs.

2 and .3, legends 28 upon the top mum of the-upper section cooperating with the hanclle, 27 to indicate when, the valve stem 22 has been shiftedto eithergan open or closed position. I

The burner includes an angle pipe haying. a horizontal leg 29. extendingthrough the side wall oftheupper section 1 and an inner. depending vertical leg'30 disposed; the en d of .the passage 13 as shown in'Fig. 5, the; lower endof the burner-pipe section 30..extendingthrough the upper wall of the gas chamber and terminating at a point above tl1e bottom wall 5 thereof. A burner, tip 31 is carried by the outer end of the horizontal leg 29 of the burner pipe and passes through the axial bearing block 32 of the reflector plate 33, the peripheral edge of the gaschamber extending outwardly of theside wall of the-upper lamp section 1 to provide a support for the reflector block 32 as shown in Fig. 2.

. Thelamp pick 34- carrying a spring arm '35 adjacent the head 36 thereof is adapted to be carried in a re-latively small axial: opening formed in the upper end of the valve stem 15 as shown in Fig. 2 and is the spring arms 38 are provided tofurther maintain a rigid .support' therefor. Out- ,a gripping surface combined witli the Iprowarolly projecting ribs 39 are carried by the side wall of the lowersect1on 2 to provide tuberances 7 to facilitate the connection'and disassembling of thelamp section.
